nd 3-321-E
The status of projects 2-319-E and 3-321-E is approximately 80% complete.
The Instruction Handbook for the use of the catalog is being edited for
the final report. To date the status of the catalog work is as follows:
Number of data sheet transcriptions 1550
Number of finished punched cards/file 410
The financial status of the projects is as follows:
Total expenditure of 2-319-E
$35,301.69
Total expenditure of 3-321-E
14,680.51
Balance as of 15 January, 2-319-E
7,840.31
Balance as of 15 January, 3-321-E
10,229.49
At the present time there are two full-time technicians transcribing data
from catalogs, coding, and notching the punched cards. Their present
rate of production is 500 transcriptions per week. The rate of expenditure,
including all personnel and supplies, is of the order of $500. per wedc.
The following items are submitted for your comment and/or approval.
1. The "Procedure for use of Punched Card Index" has been rewritten
with the inclusion of a sample card. Final reproduction of the HandboOk
will be delayed pending your approval of the attached copy of this rewrite.
2. The scope of work, defining the two projects is not clear as to
whether or not file cabinets are to be included with the catalogs. If
file cabinets are required, then it is desirable to include a vibration
table with each file. The use of a vibration table greatly reduces the
work required for a given selection, and increases the probability of
obtaining all cards that are punched according to the desired code.
3. If cabinets are required, then approval is requested of the enclosed
file drawer design sketch. This design estimates at approximately $18
per drawer.

II. PROCEDURE FOR USE OF TRANSDUCER AND ACTUATOR INDEX
Unisort cards measuring 5 by 8 inches are used in this index. These cards
have a double row of holes on each side, and four holes per linear inch.
The indexing of these cards is done by using 11 punched hole codes which are
arranged on the card as shown in Figure 2.

The procedure for locating an actuator or transducer, or punching of cards is
as follows:
Code 1. The quantity to be measured or actuated is found in the "List
of Measurable Physical Quantities" (alphabetized). When the parameter
can be measured or actuated directly, the particular code to be used in
Code 1 will be found opposite the term. In this and all other codes which
involve deep and shallow holes, the deep holes will be designated by a line
underscoring the code number. When the quantity cannot be found or a code
is not given opposite the parameter, a device for performing the job
is not on the market at the present time. The task, therefore, is left to
the ingenuity of the designer. Also given in the list of "Measurable
Physical Quantities" are the MLTQ units of the quantity which are also the

units that are used in the sensitivity code. The reciprocal of the sensitivity
units is used as the range (code 2) units. The application of the device
on the sample card, Figure 3, is Pressure; locating this quantity in fne
list of "Measurable Physical Quantities" it is seen that the code is 257 234,
thus the punches are made appropriately.
Code 2. The Range of Variation of the quantity to be measured or
actuated is selected according to the mnemonic printed on the punched card.
This code is broken up into three units. The first, for the digit of the
lower end of the range. The second, for the power of ten from the low
end to the high end of the range. This unit will be punched in series,
i.e., when a transducer has a range from 4 x p-1 to 6 x 1041 this unit
will be punched 10-1, 1091, 1011'102, 103, 104. The third unit is the
code for the digit of the upper end of the range. The units of the range
code will be the reciprocal of the sensitivity unit. A given number is
coded or located by notching the holes whose diagonals intersect at the
number. In this code, a distinction must be made between the upper and
lover figures. In the mnemonics used in this index two punches are required
to indicate one number; one deep, and one shallow. For the upper number
at the intersection of diagonals the deep punch is one the left, for the
lover number the deep punch is on the right. Referring to Figure 3, the
lower range digit is 0, the power often of the range is 10-3, 10-2, 10-1,
the upper range digit is 3, the closest inclusive digit is 2, therefore
theiappropriate holes have been notched.
Code 3. In the event that the associated amplifier or modification
network electrical characteritics are known, it is possible to select units
on the basis of their operating principle. This is done by referring to
the chapter entitled "Operating Principles" to locate the holes that must
be picked in order to select the desired operating principle. In Figure 3,
the sample card is of the strain gage type, which is catalogued as "Variable
Resistance, Crosssection," therefore the proper holes are notched 234.
Code 4. This code is used to separate the transducer cards from
the actuator cards. TWO holes are used; the first for transducer (T),
the second for the actuator (A). Referring to Figure 3, since the input
is mechanical and the output is electrical, the device is a transducer,
therefore the appropriate hole is notched.
Code 5. This code permits the user to select a transducer Or actuator
according to the electrical variable parameter. The code consists of six
linear holes labelled RILIC;F,V?I- which stand for variable resistance,
inductance, capacitance, frequency voltage, and current. The deep holes
in this code will not be used. Referring to Figure 3, since the device
operates by changing its resistance the electrical variable is notched
R.
Code 6. The sensitivity code consists of seven holes, and a printed
mnemonic. This code is used to express the power of ten of the magnitude
of the sensitivity which is expressed as the change in output parameter
per unit change of input parameter for a transducer, and vice versa for--
the actuator, e.g. 2MV/?C, or 3 in oz/ampere. The mnemonic for this code

is used exactly as the one for the range code. Referring to Figure 3,
the sensitivity is .053V/PSI (on 5.3 x 10-2); therefore the appropriate
holes are punched.
Code 7. This code, which gives the type of modulation of the electrical
signal, consists of three holes labelled AM, FM, PM which stand for
amplitude modulation, frequency modulation, and pulse modulation:. The
deep holes are not used. Referring to Figure 3, the device varies
resistance in a continuous manner. This has no effect on frequency,
therefore the appropriate hole, AM, is notched.
Code 8.. This code is the volume or size code. It consists of
four holes, labelled 0,l,213 which stand for the power of ten of the
volume expressed in cubic inches, 1, 10, 100, 1000 cu. in. The deep
holes will not be used. Referring to Figure 3, the size is 6 Cu.. in.,
therefore the hole labelled, 1, is punched. The next larger power of
ten is always used; !,:g. the code is inclusive.
Code 9. This code, which states the dynamic frequency range of the
input or output variable, consists of seven holes. The holes are labelled
S? 1,213,4, 4.3,5; each stands for the power of ten of the frequency
(static, 10 cps, 100 cps 1000 cps, 10,000 .cps, 20,000 cps, 100,000 cps).
The deep holes are punched only when the device responds from static
to some higher value. _Referring to Figure 3, the device is useful over
the range from 0 to 10--'cps; therefore S.mas punched deep, 1 was punched
deep. -474
Code 10.. This code describes the type and amount of electrical
power, other than signal poWer, required to make the device operate. The
code consists of six double holes labelled:
A = active, auxiliary power not required
-1= 0.1 watt
0 = 1.0 watt
1 = 10.0 watts
? 2 = 100.0 watts
3 . 1000.0 watts
The shallow holes indicate AC power required; the deep holes that DC power
is required. Referring to Figure 3, 0.2 watts either AC or DC is required,
therefore the deep hole is notched.
Code 11. This is the manufacturerts code and is set up for use in
servicing the index. The names of the manufacturers are listed in
alphabetical order and have a code listed beside them. When new literature
is obtained from the manufacturer, all of his cards may be dropped out
and perused for the new material to determine whether or not it is duplicated.
It is understood that the codes punched for a particular device will include
the capabilities of the device and will not magnify them. The remainder
of the ?holes are not utilized; however, they can be used for future
expansion of the code. 1
